1: IEC60730/60335 certified by VDE.

2: An older version of Self Test Library.
The certificate was obtained by Renesas from VDE, but the related application notes and sample codes are for customers who continue using an older version of the Self Test Library.

3: Application Notes and Sample Code for customers new to the Self Test Library.

4: For application notes about peripherals related to the safety functions of RL78/G23, please visit the RL78/G23 product webpage.

5: You can check certification information at TÜV Rheinland's certification database site.
